The expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).
<h3>What is potential energy?</h3>
Potential energy is any type of energy stored to perform physical work in a given period of time.
Conversely, kinetic energy is motion (movement) energy used when performing physical work.
In conclusion, the expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).

At first situation, ratio = x/y = 1/5
5x = y -------Equation (i)
Now, after adding 5 more red, it is = x + 5 / y+5 = 1/3
y+5 = 3(x + 5)
y + 5 = 3x + 15
y - 3x = 15 - 5
Substitute the value of y from equation (1),
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5

The Twelve Tables (aka Law of the Twelve Tables) was a set of laws inscribed on 12 bronze tablets created in ancient Rome in 451 and 450 BCE. They were the beginning of a new approach to laws which were now passed by government and written down so that all citizens might be treated equally before them.Apr

Explanation:
Due to constructive interference, we can predict that: C. the resulting wave would travel at 4.2 hertz.
<h3>What is constructive interference?</h3>
Constructive interference of a wave can be defined as a phenomenon through which two waves of the same frequency and phase combines to form a wave of higher magnitude.
This ultimately implies that, the constructive interference of a wave causes an increase in the amplitude or frequency of waves.
Due to constructive interference, we would have:
Wave = 3 + 1.2
Wave = 4.2 hertz.
